This corner has a collapsed box that I decided to let be this year because of the large population of volunteer snapdragons from last season.   The box contains 8 habeneros, 2 cucumbers, 1 eggplant, and 1 Cleome that I planted.  In the bottom left corner is part of the pineapple mint container which is on its third or fourth year.  Next season I’ll have to replace this box and since it supports edibles I can’t use treated wood.  This pine box painted with white polyurethane paint was built for the 2007 season so it has lasted only 6 years — which might not be so bad.  The treated wood boxes on the veranda level are on their 11th year and show no signs of wear.  I need to figure out a way to line the inside of these large box containers with some kind of plastic to protect the wood from soil moisture without introducing nasty chemicals that can get into edible plants.

Here’s the box in 2007 on SE wall main roof.
